The Gunners have seen new signings Shkodran Mustafi and Granit Xhaka make a positive impact since their arrival in the summer, something which has helped them stay within two points of top spot.

Parlour believes that Arsenal are in good shape in their title challenge, and thinks that a win at Old Trafford would send out a statement to the rest of the league.

Strong spine

“I look at Arsenal now and think they’re a lot stronger,” he added.

“People were always waiting for that big centre forward, but the key signings for me were Mustafi and Xhaka. Those two down the spine have been very strong, especially Mustafi who’s come in next to Koscielny at the back.

“No disrespect to Per Mertesacker, who’s getting that little bit older, but sometimes Arsenal have to sit off with him in the team. With Mustafi, you can push up that little bit higher and condense the space in midfield.

“It’s worked so far, but it’s such a competitive league and this will be a big test. If they’re going to win the title, they have to go to places like Old Trafford and try to get a result.”
